Curious to know how a stud conversion kit works for your car? I've personally ran the Motorsport Hardware stud conversion kits on all of my BMW M3's that I've had from E90 to E92 to F80 M3. Motorsport Hardware also has multiple sized spacers for sale to help get that perfect fitment on your BMW M3.
They make life x10 easier when it comes to changing wheels and swapping out brake pads etc. They also give you car a track look plus you can pick the finishes of your bolts/studs. You'll have much more thread to work with in order to place a spacer on your wheel to give your car a better fitment/more flush with your fender. Motorsport Hardware also sells spacers, which makes a great pair with their conversion kit.
Peace of mind to have much more thread to work with, along with making it easier for yourself. Take a look below on some detailed information on what they do and how they work plus a full guide in installs between written format and video format (DIY install videos)

Please note that lug bolts and studs/nuts are wearable items so proper care must be practiced to ensure their longevity and service life.
If you are racing, it is good practice to replace wheel bolts studs/nuts every season or every other season based on frequency of track events.
Washing the car: when finished, drive the car around the block to remove any excess or sitting water in the lug bolt holes.
Living in snowy climates: It is good practice to apply a small amount of anti seize onto the nuts to prevent seizure.
